#1205 new System Defect

10.0: recent update results in fatal grub error

Description

Thinkpad x201 with pcbsd full-disk zfs installation.
While I hadn't used it for a couple of days, I booted the machine the day before yesterday. It installed package updates and then informed about a conversion to a new pbi system.
All appeared to go smoothly until the reboot.
The machine is currently unusable, grub panics into rescue shell telling:

error: symbol 'grub_term_highlight_color' not found.
Entering rescue mode...
grub rescue>

I tried booting from stick in order to edit grubs config, but could't mount the fs.
Googling revealed that Debian folks went through exactly the same calamities a couple of months ago. Hence it appears to be a known bug in grub.
Anyway it keeps me from using pcbsd and accessing my data.
Please advise!
